ABSTRACT
AIM:
To investigate the role of G?q/11-mediated signal transduction pathway in cardiac hypertrophy induced by angiotensin II (AngII).METHODS:
Renal hypertension was performed by placing a sliver clip around the left renal artery(2K1C). Hemodynamic parameters, the ratio of left ventricular weight to body weight, the AngII contents and the activities of phospholipase C (PLC) in myocardium were measured at 1st, 2nd, 4th and 8th week after operation, respectively. The levels of G?q/11 were assayed by Western blot analysis. -leucine incorporation and levels of G?q/11 were measured in cultured neonatal rats ventricular myocyte after AngII stimulation.RESULTS:
In 2K1C group, blood pressure and the ratio of left ventricle of heart to body weight were significantly increased compared with sham group between 2nd to 8th week. AngII content increased from 1st to 8th week after operation. Compared with the sham group, levels of G?q/11 in 2K1C group increased by 25.0% and 35.8% at 4th and 8th week( P
